Renewed Apri1 4,'1931.

This invention relates to furniture and more particularly to a chair or seat adapted to support a person and which is connected to a table or desk in such a manner as to be pivotally swung towards or away therefrom, as the case may be. i

It is an object of the present invention to provide a swinging seat adapted to be swung under a desk out of the way and at the same time lock the seat in such a manner as to prevent it coming in contact with any portion of the desk so as to damage the latter.

Another object of the invention is to provide a partially oscillating seat pivotally connected to the legof a deskor other supporting structure which, when in its normal inward position under the desk, is prevented from oscillating, but when in its normal outward position is permitted to oscillate through a limited are but not sufficient to permit the back of the seat to engage and injure the desk or other supporting structure.

Another object of the invention is to provide a seat, of the type referred to, which when in its normal outward position can be moved to its normal inward position beneath the desk or supporting structure and be automatically oscillated to properly position the 7 seat beneath the desk and-to maintain the same in proper position thereunder so that the seat cannot be oscillated thereby preventing injury to the desk or supporting structur'e.

Heretofore, pivoted seats have been provided and employed in connection with counters, desks and other supporting structures, but the seat is of the customarytype without a back rest so that the seat can be oscillated without interference with the supporting structure, but where backs have been employed in connection with the pivoted seats, these backs engage with the supporting structure when the seat is swung about its pivot which usually results in marring the supporting structure. These seats are furthermore usually supported by the floor and as the pivotal movement of the seat is limited by the engagement of the back with the supportingrstructure, it is usually very inconvenient for the occupant to mount these seats because ofthe restricted pivotal movement thereof. NVith the present structure and arrangement, applicant has avoided this obj ection by prov ding a seat having a supporting back which is pivotally connected to the leg of the desk or other supporting structure,

the seat of which is further mounted for a predetermined oscillatory movement indei pendently of its pivot connection so that the seat can be swung about its pivot away from;

the desk and then theseat oscillated independently which permits the occupantto leave the seat without interference by the desk'or supporting structure. This arrangement further permits the occupant to also. properly position himself with respect to the desk or other supporting structure to suit h1s own condltions, inasmuch as it is the desire of some persons to be positioned close to tional view of the seat in its normal inward. position beneath the desk or supporting structure which isindicated by dotted lines;

In'the drawings, 10 represents a desk or other supporting structure having a plurality of depending legs 11 which are suitably supported by a floor or other structure. The seat is indicated at 12 and has a back portion 13 connected to the seat by means of a pair of resilient braces 14 which are bolted or otherwise secured respectively to the seat and back portions. This seat is adapted to be swung beneath the desk when the same is not being used and to be swung outwardly from beneath the desk when it is desired to be occupied, and the operating mechanism for the seat, which will be hereinafter more fully described, prevents engagement be tween the backportion 13 and the desk 10 while the seat is being moved, thereby preventing damage or marring of the desk.

The seat 12 is provided on its under surface with a casting 15 which is bolted or otherwise secured thereto, and has extending downwardly therefrom a seat post or stud 16.

The seat 12 is supported in a horizontal position by a bracket which comprises a spider 17 having at one side a cylindrical integral leg or support 18, the lower end of which extends below the spider 17 and has bifurcated ends 19 between which is rotatably supported a rubber tire wheel or caster 20 adapted to engage and be moved upon the floor. The upper end of the leg 18 is provided with a central bore 21 of a diameter suflicient to rotatably receive therein the stud 16 of the seat 12. A thrust ball 22 is positioned at the end of the bore 21 and is adapted to be engaged by the end of the stud 16 to thereby permit the stud 16 carrying the seat 12 to be more freely oscillated about its axis. The bore 21 is provided with a pair of counterbores 23 slightly larger than the diameter of the stud 16 and adapted to retain a quantity of oil introduced therein for the purpose of lubricating the stud 16.

The end of the spider 17 opposite the cylindrical support 18 is provided with a pair of extensions or lugs 24 horizontally spaced apart and provided with apertures adapted to suitably receive therein a vertical pin or.

rod 25 about which the bracket is pivoted.

These lugs or extensions 24 are positioned between a pair of lugs 26 extending outwardly and formed integral with a triangular shaped bracket 27 bolted or otherwise secured to one of the legs 11 of the desk 10, the upper and lower ends of the pin 25 being suitably mounted in the lugs 26 so that the spider 17 is permitted to pivot about the pin 25 when the seat is moved under or away from the desk. t will be noted from the construction so far described that the weight of the occupant seated upon the seat is carried entirely by the cylindrical leg 18 thereby eliminating any load upon the connection between the leg of the desk 10 and the spider 17, this connection functioning entirely as a pivot about which the seat 12 is swung.

When the seat 12 is in its normal inward position, as shown in Fig. 1, it will be noted that the back 13 is adjacent the top of the desk 10 and it is desirable to prevent engagement or interference between the back and the desk to thereby prevent marring or injury of the desk. It is, therefore, advisable to provide a means for preventing the seat 12 from oscillatory movement about the stud 16 and this is accomplished in the following manner. The cylindrical leg 18 is provided with a lateral extension 28 formed integral with the upper portion of the leg and is adapted to engage with a depending pin or stop 29 secured in the lower portion of the casting 15 upon the underside of the seat 12. A lever or arm 30, as shown in Fig. 4, is provided with a substantially centrally located aperture 31 adapted to be freely mounted upon the stud 16 between the upper portion of the cylindrical leg 18 and the underside of the ing pin or stop 29, as clearly shown in 3, so as to prevent oscillation of the seat 12 beyond a certain point. The opposite end of the lever 30 is bifurcated, as at 33, and is pivotally connected by a pin 34 to one end of a link 35 while the opposite end of the link is pivotally connected by a pin 36 between the bifurcated ends 37 of an extension 38 ex tending outwardly and formed integral with the upper portion of the triangularlv shaped bracket 27. This linkage mechanism, just described, is of such a nature that the lever or arm 30 has a straight line motion which inasmuch as the depending pin or stop 29 engages with the end 32, prevents oscillation of the seat 12 in a counter-clockwise direction whether in its normal position beneath the desk or in its outward position.

When the seat 12 is in its normal inward position beneath the desk, as indicated by.

dotted lines in Fig. 3, it will be seenthat the depending pin or stop 29 is maintained between the end 32 of the link 30 and the extension 28 of the cylindrical leg 18 so that the seat 12 is prevented from any oscillatory movement about its vertical. axis, the back 13 being prevented thereby from engagement with the desk 10.

When the seat is moved to its normal outward position, as indicated in full lines in Fig. 3, the end 32 of the link 30 and the extension 28 of the cylindrical leg 18 have been moved away from each other and the depending pin or stop 29 is, therefore, in engagement with only the extension 32. seat is. therefore, prevented from rotation about its vertical axis in a counter-clockwise direction by the engagement between the extension 32 and the pin 29 but is permitted to be moved in a clockwise direction about The gagement between moved to the position indicated in dotted lines, at which time it engages with the-extension 28 and is prevented from further movement in that direction. However, when the pin or stop. 29 is in such engagement, the seat 12 has been oscillated about its vertical axis through an arc ofsubstantially degrees which thereby permits the occupant" to either leave or seat himself upon the seat 12 without interference by the desk.

When the seat 12 is in its normal outward position and the .seat hasbeen oscillated in a clockwise direction until the stop 29 -is in ment until the pin 29 is again retained be-- tween the ex-tenslon 32 and the extension 28.

During this time the back13 has been moved from a position at right angles to the front edge of the desk to a positionsubstantially parallel with the front edge of the desk 10 and the back has been prevented from being moved into engagement with the desk 10;

It might be stated that independently of the position of the seat 12 between its normal inward position and its normal outward position the seat 12 cannot be oscillated about its vertical'axis to bring the back 13 into engagement with any portion of the desk 10, 1 thereby preventing of the desk.

Further, it should be understood that this seat can be attached opposite to that shown in the drawings so that the seat can be swung any injury or marring in the opposite direction as already described,

it being only necessary to change the bracket 27 from a left hand bracket, as shown, to a right-hand bracket, reversing the position of the lever 30 and changing the position of the depending pin from that shown in the drawings to the opening 39 provided upon the' -'of a pivoted seat, a support for said seat,

means for pivotally connecting said support I under face of the casing 15.

lVhile I have described the preferred construction and arrangement of the seat em-' bodying the present invention, it is to be understood that modifications and changes may be resorted to without departing from the spirit of the invention as defined in the appended claims. 7
